The 'grimmy contest' later developed into the 'pig pot'. Similar rules, but , shall we say, it involved an act rather more intimate than dancing...
On one occasion (it might have been during the SAC Bomb/Nav contest at Ellsworth AFB, Rapid City?), it seems that the 'pig pot' had risen to several hundred dollars, yet no-one had summoned up sufficient courage to brave a...'liaison' with the spectacularly obvious potential target, later to be known as 'Mrs Doubtfire'...
Eventually one of the AEOs (it had to be, really) sidled up to the obnoxious mound of blubber and said "Look, K****, why don't we just
say that we did the deed - and I'll split the pot with you 50/50?".....
I gather that she was less than impressed - but as for the eventual fate of the 'pig pot' in question, of that I am unaware.
